The best time to change the oil

Engine oil is called the "blood" of the engine, and its health directly affects the service life of the engine. The oil needs to be replaced after a period of time. When is the best time to change the oil?

Why change the oil

After the engine oil runs at high temperatures, its physical and chemical properties will change. With the infiltration of external impurities and oxidation reactions, the engine oil gradually loses its lubricating performance and increases the wear rate of mechanical parts. It must be replaced in time.

All other moving parts rely on oil to dissipate heat. If the viscosity is too high and the oil flow rate per unit time is small, the cooling effect of the parts will be much worse.

Correspondingly, if the parts are not cooled well, their service life will be reduced. In addition, the kinematic viscosity is too large, and the fuel economy is definitely not good. Therefore, choosing a suitable viscosity oil is the greatest protection for the engine.

When is the appropriate time to change the engine oil?

So the question is, when is the best time to change the oil? If you change it early, you will feel that the service station wants to make money for you, and worry that the engine will continue to fail after the change is too late.

Usually there is a fixed mileage and time to change the oil. However, the oil change interval must be shortened in the case of harsh engine working conditions, such as dusty, humid, and severe cold environments. When the following conditions occur in the vehicle, it means that the vehicle should also be replaced with oil!

1

Oil pressure is too low

Too little oil storage will result in no or little oil in the lubrication system. Dirty or thick oil will cause the oil pump to be unable to effectively suck in or pump out the oil. This will cause the oil pressure to be too low. At this time, the oil must be replaced in time.

2

Oil pressure is too high

Excessive viscosity of the oil, deterioration of the oil and gumming lead to reduced fluidity of the oil, blockage of the filter element or oil passage, etc. will cause the oil pressure to rise. Excessive oil pressure will cause carbon deposits in the engine cylinders, and will also reduce the life of the engine.

3

OIL Sludge appears

Failure to change the engine oil on time will result in increased oil sludge, which will lead to clogging of filters and oil holes, resulting in difficulty in lubrication of the engine and aggravated engine wear.
